It was discovered that there was an integer overflow in libnl3, a library for dealing with netlink sockets.

A missing check in nlmsg_reserve() could have allowed a malicious application to execute arbitrary code within the context of the WiFi service.

For Debian 7 β€˜Wheezy’, this issue has been fixed in libnl3 version 3.2.7-4+deb7u1.

We recommend that you upgrade your libnl3 packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
